We were given a pair of parakeets from a friend. We'd had them in the past, and even when we had male and female we could never get them to breed. Well, these two immediately got busy. After the first two clutches we planned to remove the nest box, but she started laying even before the last two left the nest. After the third clutch, we moved her into a cage on her own, without a nest box, as soon as the babies started growing decent feathers. However, once all four left the box we moved the father to the female's cage to keep her company, and they immediately began mating. Since there is no nest box in that cage, will she become egg bound if we don't put it back, or can she somehow prevent becoming gravid? How long should we have kept them apart, or is there anything we can do to stop them and keep her healthy?
